CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of priority to U.S. Provisional Patent Application No. 60/870,339, filed 15 Dec. 2006 and U.S. Provisional Patent Application No. 60/953,595, filed 2 Aug. 2007. The full disclosures of these applications are incorporated herein by reference in their entirety and for all purposes.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention provides compounds, pharmaceutical compositions comprising such compounds and methods of using such compounds to treat or prevent diseases or disorders associated with the activity of Cannabinoid Receptor 1 (CB1).

2. Background

The cannabinoids are psychoactive ingredients of marijuana, principally delta-9-tetrahydrocannabinol. Two cannabinoid receptors have been cloned, CB1 and CB2. CB1 is predominantly expressed in the central nervous system whereas CB2 is expressed in peripheral tissues, principally in the immune system. Both receptors are members of the G-protein coupled class and their inhibition is linked to adenylate cyclase activity.

The novel compounds of this invention inhibit the activity of CB1 and are, therefore, expected to be useful in the treatment of CB1-associated diseases or disorders such as, but not limited to, psychosis, memory deficit, cognitive disorders, migraine, neuropathy, neuroinflammatory disorders, cerebral vascular accidents, head trauma, anxiety disorders, substance abuse (such as smoking cessation), stress, epilepsy, Parkinson's disease, schizophrenia, osteoporosis, constipation, chronic intestinal pseudo-obstruction, cirrhosis of the liver, asthma, obesity, and other eating disorders associated with excessive food intake.

Pharmacology and Utility

Compounds of the invention inhibit the activity of CB1 and, as such, are useful for treating diseases or disorders in which the activity of CB1 contributes to the pathology and/or symptomology of the disease. This invention further provides compounds of this invention for use in the preparation of medicaments for the treatment of diseases or disorders in which CB1 activity contributes to the pathology and/or symptomology of the disease. CB1 mediated diseases or conditions include, but are not limited to, metabolic disorders as well as conditions associated with metabolic disorders including obesity, bulimia nervosa, compulsive eating disorders, diabetes, arteriosclerosis, hypertension, polycystic ovary disease, osteoporosis, cardiovascular disease, osteoarthritis, dermatological disorders, hypertension, insulin resistance, hypercholesterolemia, hypertriglyceridemia, cholelithiasis and sleep disorders, and hyperlipidemic conditions; or psychiatric disorders such as substance abuse, psychosis, depression, anxiety, stress, epilepsy, mania and schizophrenia; or cognitive disorders such as dementia including Alzheimer's disease, memory deficits, short term memory loss and attention deficit disorders; or neurodegenerative disorders such as Parkinson's Disease, cerebral apoplexy and craniocerebral trauma, hypotension, catabolism in connection with pulmonary dysfunction and ventilator dependency; or cardiac dysfunction including valvular disease, myocardial infarction, cardiac hypertrophy and congestive heart failure); or the overall pulmonary dysfunction, transplant rejection, rheumatoid arthritis, migraine, neuropathy, multiple sclerosis, Guillain-Barre syndrome, the inflammatory sequelae of viral encephalitis, cerebral vascular accidents, inflammatory bowel disease, lupus, graft vs. host disease, T-cell mediated hypersensitivity disease, psoriasis, asthma, Hashimoto's thyroiditis, Guillain-Barre syndrome, cancer, contact dermatitis, allergic rhinitis, ischemic or reperfusion injury, head trauma and movement disorders. The compounds are also useful for the treatment of substance abuse disorders, particularly to opiates, alcohol, marijuana, and nicotine including smoking cessation. The compounds are also useful for the treatment of eating disorders by inhibiting excessive food intake and the resulting obesity and complications associated therewith, including left ventricular hypertrophy. The compounds are also useful for the treatment of constipation and chronic intestinal pseudo-obstruction, as well as for the treatment of asthma, osteopororsis, and cirrhosis of the liver.

Marijuana and its derivatives have been used for centuries for medicinal and recreational purposes. A major active ingredient in marijuana and hashish has been determined to be Δ9-Tetrahydrocannabinol (Δ9-THC). The biological action of Δ9-THC and other members of the cannabinoid family occurs through two G-protein coupled receptors termed CB1 and CB2. The CB1 receptor is primarily found in the central and peripheral nervous systems and to a lesser extent in several peripheral organs.

The CB2 receptor is found primarily in lymphoid tissues and cells. Three endogenous ligands for the cannabinoid receptors derived from arachidonic acid have been identified (anandamide, 2-arachidonoyl glycerol, and 2-arachidonyl glycerol ether). Each is an agonist with activities similar to Δ9-THC, including sedation, hypothermia, intestinal immobility, antinociception, analgesia, catalepsy, anti-emesis, and appetite stimulation.

The genes for the respective cannabinoid receptors have each been disrupted in mice. The CB1 receptor knockout mice appeared normal and fertile. They were resistant to the effects of Δ9-THC and demonstrated a strong reduction in the reinforcing properties of morphine and the severity of withdrawal syndrome. They also demonstrated reduced motor activity and hypoalgesia. The CB2 receptor knockout mice were also healthy and fertile. They were not resistant to the central nervous system mediated effects of administered Δ9-THC. There were some effects on immune cell activation, reinforcing the role for the CB2 receptor in immune system functions.

Excessive exposure to Δ9-THC can lead to overeating, psychosis, hypothermia, memory loss, and sedation.

Treatment of asthma with CB1 receptor modulators (such as CB1 inverse agonists) is supported by the finding that presynaptic cannabinoid CB1 receptors mediate the inhibition of noradrenalin release.

Treatment of cirrhosis of the liver with CB1 receptor modulators is supported by the finding that a CB1 receptor modulator will reverse the low blood pressure observed in rats with carbon tetrachloride-induced liver cirrhosis and will lower the elevated mesenteric blood flow and portal vein pressure.

In accordance with the foregoing, the present invention further provides a method for preventing or treating any of the diseases or disorders described above in a subject in need of such treatment, which method comprises administering to said subject a therapeutically effective amount (See, “Administration and Pharmaceutical Compositions”, infra) of a compound of Formula I or a pharmaceutically acceptable salt thereof. For any of the above uses, the required dosage will vary depending on the mode of administration, the particular condition to be treated and the effect desired.

Administration and Pharmaceutical Compositions

In general, compounds of the invention will be administered in therapeutically effective amounts via any of the usual and acceptable modes known in the art, either singly or in combination with one or more therapeutic agents. A therapeutically effective amount can vary widely depending on the severity of the disease, the age and relative health of the subject, the potency of the compound used and other factors. In general, satisfactory results are indicated to be obtained systemically at daily dosages of from about 0.03 to 2.5 mg/kg per body weight. An indicated daily dosage in the larger mammal, e.g. humans, is in the range from about 0.5 mg to about 100 mg, conveniently administered, e.g. in divided doses up to four times a day or in retard form. Suitable unit dosage forms for oral administration comprise from ca. 1 to 50 mg active ingredient.

Compounds of the invention can be administered as pharmaceutical compositions by any conventional route, in particular enterally, e.g., orally, e.g., in the form of tablets or capsules, or parenterally, e.g., in the form of injectable solutions or suspensions, topically, e.g., in the form of lotions, gels, ointments or creams, or in a nasal or suppository form. Pharmaceutical compositions comprising a compound of the present invention in free form or in a pharmaceutically acceptable salt form in association with at least one pharmaceutically acceptable carrier or diluent can be manufactured in a conventional manner by mixing, granulating or coating methods. For example, oral compositions can be tablets or gelatin capsules comprising the active ingredient together with a) diluents, e.g., lactose, dextrose, sucrose, mannitol, sorbitol, cellulose and/or glycine; b) lubricants, e.g., silica, talcum, stearic acid, its magnesium or calcium salt and/or polyethyleneglycol; for tablets also c) binders, e.g., magnesium aluminum silicate, starch paste, gelatin, tragacanth, methylcellulose, sodium carboxymethylcellulose and or polyvinylpyrollidone; if desired d) disintegrants, e.g., starches, agar, alginic acid or its sodium salt, or effervescent mixtures; and/or e) absorbents, colorants, flavors and sweeteners. Injectable compositions can be aqueous isotonic solutions or suspensions, and suppositories can be prepared from fatty emulsions or suspensions. The compositions can be sterilized and/or contain adjuvants, such as preserving, stabilizing, wetting or emulsifying agents, solution promoters, salts for regulating the osmotic pressure and/or buffers. In addition, they can also contain other therapeutically valuable substances. Suitable formulations for transdermal applications include an effective amount of a compound of the present invention with a carrier. A carrier can include absorbable pharmacologically acceptable solvents to assist passage through the skin of the host. For example, transdermal devices are in the form of a bandage comprising a backing member, a reservoir containing the compound optionally with carriers, optionally a rate controlling barrier to deliver the compound to the skin of the host at a controlled and predetermined rate over a prolonged period of time, and means to secure the device to the skin. Matrix transdermal formulations can also be used. Suitable formulations for topical application, e.g., to the skin and eyes, are preferably aqueous solutions, ointments, creams or gels well-known in the art. Such can contain solubilizers, stabilizers, tonicity enhancing agents, buffers and preservatives.

Compounds of the invention can be administered in therapeutically effective amounts in combination with one or more therapeutic agents (pharmaceutical combinations). For example, synergistic effects can occur with other substances used in the treatment of diseases or disorders, such as, psychosis, memory deficit, cognitive disorders, migraine, neuropathy, neuroinflammatory disorders, cerebral vascular accidents, head trauma, anxiety disorders, stress, epilepsy, Parkinson's disease, schizophrenia, substance abuse disorders such as smoking cessation, osteoporosis, constipation, chronic intestinal pseudo-obstruction, cirrhosis of the liver, asthma, obesity, and other eating disorders associated with excessive food intake, obesity, etc. (see “Pharmacology and Utility”, supra).

The latter also applies to cocktail therapy, e.g. the administration of 3 or more active ingredients.

Processes for Making Compounds of the Invention

The present invention also includes processes for the preparation of compounds of the invention. In the reactions described, it can be necessary to protect reactive functional groups, for example hydroxy, amino, imino, thio or carboxy groups, where these are desired in the final product, to avoid their unwanted participation in the reactions. Conventional protecting groups can be used in accordance with standard practice, for example, see T. W. Greene and P. G. M. Wuts in “Protective Groups in Organic Chemistry”, John Wiley and Sons, 1991.

In the following schemes, several methods of preparing the compounds of the present invention are illustrative. One of skill in the art will appreciate that these methods are representative, and in no way inclusive of all methods for preparing the compounds of the present invention. The radicals in the schemes are as described in the Summary of the Invention (supra). In each of the reaction schemes below, R₁ is 4-chloro-phenyl.

An illustration of the synthesis of the compounds in the present invention of Formula I is given in the following reaction schemes

An illustration of the synthesis of the compounds in the present invention of formula I, in which Z₂=CH₂ and Z₁=O, is given in Scheme 1. Succinic anhydride (I-a, n=1) or glutaric anhydride (I-b, n=2) can be converted into I-c by refluxing with the designated aniline in toluene followed by cyclization that is mediated by thionyl chloride. Reduction of I-c with DIBAL in CH₂Cl₂ under low temperature (preferably at −78° C.) give I-d, which then undergoes Friedel-Crafts reaction with an appropriate arene under acidic condition to provide I-e.

An illustration of the synthesis of the compounds in the present invention of formula I, in which Z₂=O and Z₁=O, is given in Scheme 2. Oxazolidinone II-b can be synthesized by Sharpless asymmetric aminohydroxylation of alkene II-a followed by cyclization under basic conditions (N. Barta et al. Org. Lett. 2000, 2, 2821). 3-aryl oxazolidinones II-c can then be obtained by copper catalyzed N-arylation of II-b. For procedures of Sharpless asymmetric aminohydroxylation, see Sharpless, K. B. et al. (1996). “N-Halocarbamate salts lead to more efficient catalytic asymmetric aminohydroxylation.” Angew. Chem. Int. Ed. Engl. 35(23/24): 2813-2816; Sharpless, K. B. et al. (1998). “From styrenes to enantiopure α-arylglycines in two steps.” J. Am. Chem. Soc. 120: 1207-17. For copper mediated N-arylation reactions, see: Buchwald, S. L. et al. (2001). “A general and efficient copper catalyst for the amination of aryl halides and the N-arylation of nitrogen heterocycles.” J. Am. Chem. Soc. 123(31): 7727-9.

An illustration of the asymmetric synthesis of 1,5-diaryl-imidazolidin-2-one is given in Scheme 3. The hydroxycarbamate III-b can be obtained by a standard Sharpless aminohydroxylation process. Tosylation of the alcohol followed by a nucleophilic substitution with sodium azide provides azide III-d which can then be converted into III-e by a sequence of hydrogenolysis, reductive amination with p-methoxy benzaldehyde followed by in situ cyclization. The resulting imidazolidin-2-one III-e is then subjected to a copper catalyzed N-arylation to provide imidazolidin-2-one III-f, which is then followed by acidic deprotection of the p-methoxybenzyl group to yield III-g.

An alternative asymmetric synthesis of 1,5-diaryl-imidazolidin-2-one is given in Scheme 4. Styrene IV-a is converted into aminoalcohol IV-c via a standard Sharpless asymmetric aminohydroxylation (AA) reaction followed by hydrogenolysis to remove the Cbz protection group. Bis-tosylation of IV-c followed by in situ cyclization provides tosyl activated aziridine IV-d, which undergoes a LiClO₄-catalyzed configuration-inverted ring opening reaction with aniline Ar₁NH₂ to provide intermediate IV-e (Yadav, J. S.; Reddy, B. V. S.; Jyothirmai, B.; Murty, M. S. R. Synlett 2002, 53). IV-e readily cyclizes with triphosgene to provide compound IV-f. Magnesium reductive cleavage of the N-Ts group in IV-f finishes the desired 1,5-diaryl-imidazolidin-2-one IV-g.

The synthesis of racemic form of IV-g uses the same route with some simplifications, in which the racemic aziridine can be obtained directly from styrene IV-a via an iodine-catalyzed aziridination reaction using Chloramine-T as a nitrogen source (Ando, T.; Kano, D.; Minakata, S.; Ryu, I.; Komatsu, M. Tedrahedron 1998, 54, 13485). For other conditions used for aziridination reactions, see J. U. Jeong, B. Tao, I. Sagasser, H. Henniges and K. B. Sharpless, Bromine-Catalyzed Aziridination of Olefins. A Rare Example of Atom-Transfer Redox Catalysis by a Main Group Element, J. Am. Chem. Soc., 120, 6844 (1998); A. V. Gontcharov, H. Liu and K. B. Sharpless, tert-Butylsulfonamide. A New Nitrogen Source for Catalytic Aminohydroxylation and Aziridination of Olefins, Org. Lett., 1, 783 (1999) and references cited therein.

An illustration of the asymmetric synthesis of 5-substituted-4-aryl oxazolidinones is depicted in Scheme 5. Compound V-b is prepared via standard Sharpless aminohydroxylation process (K. L. Reddy and K. B. Sharpless, J. Am. Chem. Soc. 1998, 120, 1207). The intermediate carbamate is then deprotected under standard acidic conditions, which is then followed by conversion into oxazolidinone V-c with carbonyl diimidazole, or a suitable equivalent. Copper-catalyzed N-arylation yields V-d. The carboxylate ester is then reduced with sodium borohyride to give alcohol V-e, which can then be converted in to V-f via nucleophilic replacement of a corresponding mesylate with a suitable nucleophile (e.g. amines, thiol and etc.).

An alternative synthesis of 5-substituted-4-aryl oxazolidinones is shown in Scheme 6. Oxazolidinone-5-carboxylic ester VI-a is treated with sodium borohydride to give the intermediate alcohol which is then converted into tetrahydropyranyl (THP) ether VI-b. Copper catalyzed N-arylation gives VI-c, which is then subjected to acidic deprotection of the THP group, followed mesylation and nucleophilic displacement (for example, with a amine R₂NH) to give the 5-substituted analogues VI-d.

An illustration of the asymmetric synthesis of morpholinones is depicted in Scheme 7. Asymmetric aminohydroxlation of styrene VII-a is followed by conversion into ether VII-c. Deprotection of the t-butoxycarbamate group is followed by base-mediated cyclization to give morpholinone VII-d. Copper mediated N-arylation gives the morpholinone VII-e.

An illustration of the conversion of oxazolidinone VIII-a into the corresponding 1,2,3-triazole derivatives VIII-c is depicted in Scheme 8. The alcohol VIII-a is first converted into the requisite mesylate, which is then treated with sodium azide to give azide VIII-b. The azide is then subjected to copper mediated cycloaddition with an alkyne RCCH to give triazole VIII-c. For an efficient synthesis of 1,2,3-triazoles from azide and alkyne, see: P. Wu, A. K.

An alternative racemic synthesis of 1,5-diaryl-imidazolidin-2-one is described in Scheme 9. Styrene IX-a is converted into aziridine IX-b via an iodine-catalyzed aziridination reaction using Chloramine-T as a nitrogen source (Ando, T.; Kano, D.; Minakata, S.; Ryu, I.; Komatsu, M. Tedrahedron 1998, 54, 13485). Aziridine IX-b undergoes a regioselective cycloaddition reaction with aryl isocyanate OCN—Ar₂ to form compound IX-c (Nadir, U. K.; Basu, N. Tedrahedron Lett. 1992, 33, 7949). Magnesium reductive cleavage of the Ts group furnuishes the desired 1,5-diaryl-imidazolidin-2-one IX-d.

An illustration of the synthesis of 1,5-diaryl-imidazolidine-2,4-dione is given in Scheme 10. N-Aryl amino acid X-b is synthesized from α-amino acid X-a and aryl halide under the CuI-catalyzed coupling reaction condition described in Ma, D.; Zhang, Y.; Yao, J.; Wu, S.; Tao, F. J. Am. Chem. Soc. 1998, 120, 12459. Compound X-b is cyclized with potassium cyanate in acidic media to finish 1,5-diaryl-imidazolidine-2,4-dione X-c.

An illustration of the asymmetric synthesis of 5-aryl substituted pyrrolidin-2-one exemplified by structure XI-h is depicted in Scheme 11. N-Boc-protected α-arylglycines XI-c is be easily prepared via the standard Sharpless two-step process from styrenes XI-a (K. L. Reddy and K. B. Sharpless, J. Am. Chem. Soc. 1998, 120, 1207). The monoalkylated Meldrum's acid XI-e is obtained from XI-c by condensed with Meldrum's acid, followed by complete reduction of its keto functionality (M. Smrcina, P. Majer, E. Majerova, T. A. Guerassina and M. A. Eissenstat, Tetrahedron Lett. 1997, 53, 12867; B. Hin, P. Majer and T. Tsukamoto, J. Org. Chem. 2002, 67, 7365). XI-e undergoes thermal ring closure to a N-Boc-protected 3-carboxy pyrrolidin-2-one XI-f, which can be further transformed into 5-aryl substituted pyrrolidin-2-one XI-g upon treatment with TFA. Buchwald copper-catalyzed N-arylation yields XI-h in good yields.

An alternative asymmetric synthesis of 5-aryl substituted pyrrolidin-2-one exemplified by structure XII-g is depicted in scheme 12. γ-Ketoester XII-c can be prepared using a Rh-catalyzed chelation assisted hydroacylation of aromatic aldehyde XII-a with methyl acrylate XII-b (Eun-Ae Jo and Chul-Ho Jun, Eur. J. Org. Chem. 2006, 2504-2507). Asymmetric reduction of XII-c using (−)-B-chlorodiisopinocamphenylborane ((−)-DIP-Chloride) affords hydroxyl ester XII-d, which is then converted into the corresponding lactone XII-e (P. V. Ramachandran, S. Pitre, and H. C. Brown, J. Org. Chem. 2002, 67, 5315-5319.). A Weinreb amidation and Mitsunobu cyclodehydration yields the 5-aryl substituted pyrrolidin-2-one in good yield and enantiomeric purity (I. M. Bell, D.C. Beshore, S, N. Gallicchio, and T. M. Williams, Tetrahedron Lett. 2000, 41, 1141-1145).

Several new synthetic methods have recently been introduced that have made the copper catalyzed cross-coupling of most nitrogen containing functional groups to sp²-halides more accessible. (Ley et al. Angew. Chem. Int. Ed. 2003, 42, 5400). The majority of these new methods employ a variety of multidentate copper chelators that make the construction of sp²-carbon-heteroatom bonds more facile. (Buchwald et al. J. Org. Chem. 2004, 59, 5578 and references cited therein). Despite these advances, relatively high heat (≧100° C.) and long reaction times (≧24 h) are still mandatory to obtain good results. Therefore, methods with improved reactivity, broader reaction scope, and substrate tolerance are still in demand. Since many groups have exploited the donor ligand effects to improve the cross-coupling, attention has shifted away from the other vital components in the reaction. A non-obvious replacement of the conventional bases (K₂CO₃, K₃PO₄, Cs₂CO₃) with the milder cesium fluoride catalyzes the coupling of a number of amides, carbamates, and nitrogen heterocycles to aryl iodides, in many cases at room temperature. Furthermore, substrates that were incompatible with the copper catalyzed reaction employing the stronger bases may be compatible with CsF.

Optimized conditions for substrates that were incompatible with the conventional conditions (CuI, diamine, K₃PO₄ or K₂CO₃, 100-110° C.) were determined with simpler substrates. Weaker bases, such as KHCO₃, KOAc, or CsF, would avoid unwanted side reactions. Screening of these bases revealed efficient coupling of oxazolidinone 1 with aryl iodide 2 to give the product 3 in good yield at 100° C. (Scheme 1). Cesium fluoride required only 2 h, whereas KHCO₃ and KOAc required 18 h. When the same reactants were treated with CsF at 25° C. for 18 h, a nearly quantitative yield of 3 was obtained. Further experiments revealed that THF, ACN, or EtOAc (Table 2) were optimal solvents for this reaction and that a minimum of 2-2.5 equivalents of CsF were required. Since CsF showed an improved ability to promote the CuI-catalyzed reaction in this model system, its ability to promote the coupling of other substrates was investigated.

A number of control reactions were performed to show that the effect cannot simply be attributed to the presence of cesium or to fluoride, but to a synergy between CsF and CuI. When CsF is replaced by KF, K₂CO₃, or Cs₂CO₃ the yield was significantly lower at 25° C. (Table 3, Entries 5-7) and at 100° C. (Table 3, Entry 5). These reduced yields could be attributed to the reduced solubility of these salts at room temperature in ethyl acetate compared to the solubility of CsF. However, when KF and K₂CO₃ are combined with a substoichiometric quantity of CsF, a 3.5 to 10-fold increase in yield was observed (Table 3, Entries 8,9). These results suggest that some synergic effect exist between CsF and CuI to account for the dramatic increase in yield.

The reactions of several amides relevant to the claimed compounds with various aryl iodides is detailed in Table 4. These reactions were performed at 1 mmol scale with 2.5 equivalents of CsF, 5 mol % CuI, and 10 mmol % N,N′-dimethylethylenediamine in either THF or EtOAc typically for 18-24 h. We found that most amides and carbamates coupled very efficiently to aryl iodides with p- or m-substituents at 25° C., with only 4u requiring heating to 60° C. (Table 4). The efficiency of these conditions on 10 mmol scale was demonstrated at 60° C. with example 4b, proving that these conditions may be scalable. Electron-poor and electron-rich aryl halides coupled with near equal efficiency under these conditions. Overall, excellent substrate tolerance and selectivity were observed. Example 4i is noteworthy as no halide exchange was observed with these conditions. The slightly reduced yield for 4n could be explained by the steric hindrance imposed by the methyl group, or to perhaps the slightly higher expected pKa for the starting amide compared to its des-methyl congener. The proximal ester group in example 4o probably aided the formation of the Cu-coordinated intermediate, leading to a nearly quantitative yield. Furthermore, no racemization or hydrolysis was observed with these conditions, but was a problem with the conventional bases. Aryl halides with o-substituents are known to suppress the N-arylation of most substrates; this limitation was overcome by coupling those substrates at 85-100° C. (Table 4,4f-g).

The amidation of aryl bromides is summarized in Table 5. Aryl and heteroaryl bromides usually require higher reaction temperatures and/or longer reaction times than the corresponding aryl iodides. Even though a number of new ligands have been introduced by several groups to reduce these barriers, none have so far completely succeeded. When aryl bromides were subjected to our CsF promoted conditions, we obtained good to excellent results in most cases when the substrates were treated 100° C. (Table 5).

In summary, the advantages of CsF mediated coupling are as follows:

a. Cesium fluoride (CsF) promoted N-arylation reactions proceed well at room temperature with a variety of substrates whereas, for other bases, elevated temperatures are required.

b. CsF is compatible with most N-arylation reaction conditions in the art, yet CsF promotes the coupling at lower temperatures and shorter reaction times than the reported conditions.

c. The weaker basicity of CsF offers greater versatility in promoting the C—N coupling reaction of base sensitive substrates; and

d. The convenience of the milder reaction conditions proves to be more useful in combinatorial or parallel reaction formats and in large scale syntheses.

CBI Biological Assays

Homogenized membranes are prepared from CHO cell clones stably expressing a human cannabinoid receptor 1 (CB1) or human cannabinoid receptor 2 (CB2). Cells are grown and scrapped from 15 cm tissue culture plates, and then subsequently centrifuged down. Cells are washed once with cold PBS, and resuspended in ≦20 ml of Buffer A (20 mM HEPES, pH 7.4, 10 mM EDTA, EDTA-free complete protease inhibitor cocktail [1 tablet/25 ml]). The cell suspension is homogenized on ice, using a Polytron homogenizer at 25000 rpm at three intervals of 15 seconds each. The homogenate is first centrifuged at 2000 rpm on a tabletop low speed centrifuge for 10 minutes. The supernatant, after passing through a cell strainer, is then centrifuged at 50,000×g for 25 minutes at 4° C. The pellet is resuspended into buffer B (15% glycerol, 20 mM HEPES, pH 7.4, 0.1 mM EDTA, EDTA-free complete protease inhibitor cocktail [1 tablet/10 ml]). Protein concentration of the prep is determined using the BCA Protein Assay kit using BSA as standard. The membranes are aliquoted and kept frozen at −80° C.

[³H]-CP55940 Ligand Binding Assay:

Solutions of test compounds ranging from 100 μM to 0.01 nM are prepared in DMSO. The desired amount of membrane prep is diluted with ice-cold assay buffer (50 mM Tris-HCl, 2.5 mM EDTA, 5 mM MgCl₂, 0.05% BSA, pH 7.4) and vortexed well. 2 μl or less of compound is distributed into each well of a round-bottom 96-well polystyrene assay plate, followed by addition of 100 μl of diluted membranes (3-10 μg/well) and the mixture is kept on ice until the addition of hot CP55940 (final concentration of 0.5 nM). [³H]-CP55940 is diluted 1:6300 (v/v) with cold assay buffer and 100 μl is added into each well. The reaction is carried out at room temperature for 120 minutes before the membranes are harvested onto a PerkinElmer Unifilter GF/B-96 filter plate using a Packard Filtermate Harvester. After nine washes with wash buffer (50 mM Tris-HCl, 2.5 mM EDTA, 5 mM MgCl₂, 0.05% BSA, pH 7.), the filter is dried in a 37° C. oven for 30 minutes. MicroScint-20 is added and the plate sealed for scintillation counting on TopCount. EC₅₀ values are obtained by fitting the data with the sigmoidal dose response curve-fitting tool of GraphPad Prism. Eight or twelve different concentrations are used to generate a concentration response curve (using three data points per concentration).

GTPγS Binding Assay

Solutions of test compounds ranging from 100 μM to 0.01 nM are prepared in DMSO. The desired amount of membrane prep is diluted with ice-cold assay buffer (20 mM HEPES, pH 7.4, 100 mM NaCl, 10 mM MgCl₂, 0.1% Fatty acid-free BSA, 5 μM GDP) and vortexed well. 2 μl or less of compound is distributed into each well of a round-bottom 96-well polystyrene assay plate, followed by addition of 100 μl of diluted membranes (3-10 μg/well) and the mixture is kept on ice until the addition of hot GTPγS. [³⁵5]-GTPγS (Perkin Elmer NEGO30H; 1 μCi/μl, 1250 Ci/mmol) is diluted 1:1000 (v/v) with cold assay buffer and 100 μl is added into each well. The reaction is carried out at room temperature for 90 minutes before the membranes are harvested onto PerkinElmer Unifilter GF/B-96 filter plate using a Packard Filtermate Harvester. After several washes with wash buffer (20 mM HEPES, pH 7.4, 100 mM NaCl, 10 mM MgCl₂), and a rinse with 95% ethanol, the filter is dried in a 37° C. oven for 30 minutes. MicroScint-20 is added and the plate sealed for scintillation counting on TopCount. EC₅₀ values are obtained by fitting the GTP [γ-³⁵S] binding data with the sigmoidal dose response curve-fitting tool of GraphPad Prism. Six or twelve different concentrations are used to generate a concentration response curve (using three data points per concentration).

For each assay, a Cheng-Prusoff correction (Cheng and Prusoff, 1973, Biochem. Pharmacol., 22: 3099-3103) is used to convert the EC₅₀ to inhibition constant K_(i). Thus,

$K_{i} = \frac{{EC}_{50}}{1 + {\lbrack L\rbrack/K_{d}}}$

where [L] is the concentration of the radio-ligand used in the assay, and K_(d) is the equilibrium binding dissociation constant for the radio-ligand.

Food Intake and Body Weight Gain

To evaluate the efficacy of compounds of the invention on inhibition of food intake and body weight gain, genetically obese (Lep^(ob)/Lep^(ob)) mice and diet-induced obese (DIO) mice are used in acute and sub-chronic models, respectively.

Male ob/ob mice (age 7-8 weeks old, Jackson Labs, Bar Harbor, Me.) are housed in groups of four and fed commercial standard pellet diet (Lab Diet 5001, PMI Nutrition International, LLC). Diet-induced obese mice are generated using 6-7 weeks old C57BL6 mice (Jackson Labs, Bar Harbor, Me.) placed on high fat diet (D12331, Research Diets) for 12-17 weeks. All mice are maintained on a 12-hour light/dark cycle (lights on at 06:00) in a humidity- and temperature-controlled environment with free access to food and water.

The week prior to the start of each study, mice are singly housed and a habituation to treatment is performed to establish baseline food consumption and body weight. Animals are randomized into treatment groups based on their initial body weight and food consumption.

To determine the acute effects of a single administration of a compound of the invention (test compound) on food consumption, ob/ob mice are treated with either vehicle, a known antagonist as a positive control, or with test compound(s). Similarly, to determine more chronic effects of test compound on food consumption and body weight gain, DIO mice are treated with either vehicle, a known antagonist as a positive control, or with test compound(s) for up to 7-35 days. Test compounds are dosed at ranges between 0.1 up to 100 mg/kg Animals are treated one hour prior to the start of the dark cycle. Food intake and body weight are recorded manually using an electronic balance prior to treatment, 16 hours post-treatment, followed by daily measurements for up to 7-35 days after the start of study. Compound efficacy is determined by comparing food intake and body weight data between vehicle treated, standard positive control treated, and test compound treated mice.
